We look at the division of 55207760 by 121 
We want to figure out the number of times 55207760 can be divided by 121.

Going ahead to step 1:
The number 121 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 121

Let's proceed to step 2:
121 can be fit into 55 0 times, resulting in a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 121

Let's proceed to step 3:
121 goes into 552 4 times with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 484 from 552 and we're left with 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 121

Going ahead to step 4:
121 can be fit into 680 5 times, resulting in a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we take 605 away from 680, we end up with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 121

Going ahead to step 5:
When dividing 757 by 121, we get 6 with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 456.0
Subtracting 726 from 757 leaves us with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 121

Let's proceed to step 6:
121 can be fit into 317 2 times, resulting in a remainder of 75.
Use 2 as the next digit of our solution. 
Result so far: 4562.0
Subtract 242 from 317 to get 75.
Grab the next digit (6) from the dividend, add it to 75, then carry on: 756 / 121

Going ahead to step 7:
The number 121 fits into 756 6 times, leaving a remainder of 30.
The next digit of our result is 6. 
Result so far: 45626.0
If we subtract 726 from 756, we get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 121

Let's proceed to step 8:
If we divide 300 by 121, we get 2 and a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 456262.0
The remainder is 58 after subtracting 242 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
If we divide 580 by 121, we get 4 and a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 456262.4
If we take 484 away from 580, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 10:
If we divide 960 by 121, we get 7 and a remainder of 113.
Use 7 as the next digit of our solution. 
Result so far: 456262.47
Deduct 847 from 960 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 11:
The number 121 fits into 1130 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 456262.479
Subtract 1089 from 1130 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
The number 121 fits into 410 3 times, leaving a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 456262.4793
If we subtract 363 from 410, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
121 can be fit into 470 3 times, resulting in a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 456262.47933
Deduct 363 from 470 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

The final result is 456262.47933 with a remainder of 0.000107.
